Innovation on the market of beers : the barrel under pressure. These barrels of 5 liters of beer allow the consumers d'to have the pleasure pf'a draught beer at home. The gas of pressure is integrated into the barrel and a tap, is fixed easily to act as pump with beer. It is thus necessary d'to explain how the use of the tap. For that, we carried out a display made of moulded plastic and paperboard in the shape of giant barrel, capped mechanism : a valve and the pipe to serve beer. The sides of the display unit offers beautiful faces to explain the new product. The real size tap, such it is delivered with the barrel, is shown on a small shelf on a side of the display unit so that the consumer can test handling of it.
